Embodiment Construction

[0044] The method for manufacturing the pixel-defining layer of an OLED display panel provided by the embodiment of the present invention does not require a special mask, and does not require an alignment process during the photolithography process, thereby reducing production costs, simplifying the production process, and Improve product yield. In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] The pixel defining layer of the OLED display panel in the embodiment of the present invention is prepared after the active array and the anode of the pixel are prepared, and before the formation of the organic light emitting layer.

[0046] The traditional pixel definition layer usually uses a specially designed mask to pattern the pixel definition layer. The embodiment of the present invention does not req...

Abstract

Embodiments of the present invention provide an organic light emitting diode display panel and a method for manufacturing the same. The manufacturing method comprises: coating a photoresist layer on a transparent substrate with an active array formed; performing exposure on the photoresist layer from one side of the transparent substrate opposed to the photoresist layer, where the scan lines and the at least one kind of lines are used as a mask to prevent exposure of the corresponding photoresist, so that a photoresist remaining region is formed by the photoresist layer; conducting a development treatment on the photoresist layer, so that the photoresist outside the photoresist remaining region is removed and the photoresist in the photoresist remaining region is retained to form the pixel defining layer. The embodiments of the invention may simplify the fabricating flow of the display panel, reduce production costs of the display panel, and increase yield of the display panel.

Description

technical field [0001] The invention relates to the display field, in particular to an organic light emitting diode display panel and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (OLED, Organic Light-Emitting Diode) display backplane usually consists of glass substrate, ITO (indium tin oxide, indium tin oxide) anode (Anode), organic light-emitting layer (Emitting Material Layer) and cathode (Cathode), etc. The organic light-emitting layer is sandwiched between the thin and transparent ITO anode and the metal cathode. When the holes (Hole) of the anode and the electrons (Electron) from the cathode are combined in the organic light-emitting layer, the The organic material in the organic light-emitting layer is excited to emit light. Active Matrix Organic Light Emitting Diode (AMOLED, Active Matrix / Organic Light Emitting Diode) display panel is a type of OLED display panel. Compared with traditional liquid crystal display panels, A...
